It is better to go for a double sided (turnable) mattress because you will get a longer life span out of it. Everytime you flip it, it is like getting a brand new mattress. When you flip it, all the fillings spread out and it gives it a new lease of life. THe mattresses can be very heavy and sometimes people don't flip them but it is always good to have the option!
If you are concerned about over heating or getting too warm, I would avoid memory foam as some people can react with the memory foam and get very warm. Again, this does not apply to everyone and is a personal thing.
We sell a lot of natural filled mattresses for this reason. Natural filled mattresses (wool etc), don't get too warm. Another option is a gel or latex mattress which also keeps you cool.
